【Abstract】 The frost-resistance of concrete containing ground granulated blast furnace slag(GGBS), with or without fly ash , has been investigated. The test results show that the concrete with ability to resisting of quick freezing-thawing up to 300 cycles can be obtained by the adding of GGBS and superplasticizer.更多还原
